高纯钍的产生是下一代核能的前提；然而，这仍然是一项具有挑战性的任务。为此，我们在此提出一种结合结晶和相变的超简单技术。与稀土和 UO22+ 离子相比，结晶成 ECUT-68 几乎 100% 选择性吸收 Th(IV)，而从金属有机骨架 (MOF) 到无机化合物的多步相变可直接生成无机 Th(IV) 化合物，然后生成 Th(IV) 溶液，这表明其在生产高纯钍方面具有优越的应用。
The generation of high-purity thorium is the precondition for next-generation nuclear energy; however, this remains a challenging task. To this end, we present herein an ultrasimple technique with the combination of crystallization plus phase transformation. Crystallization into ECUT-68 is found to show almost 100% selective uptake of Th(IV) over rare earth and UO22+ ions, while multistep phase transformation from metal-organic frameworks (MOFs) to inorganic compounds is found to directly generate inorganic Th(IV) compound and then Th(IV) solution, suggesting its superior application in the generation of high-purity thorium.
